最后令牌批次变量 [英] Last token in batch variable

问题描述

在一个批处理文件，我怎样才能在变量中最后一个令牌不管它是否是一个数字或一个词，不管有多少令牌/词中有变量。

我将传递一个参数到批处理文件是这样的：

C：\\ execbatch.bat这是例如，一个
要么
C：\\ execbatch.bat这是例子2号

和则该批处理文件将是这样的：

 关闭@echoSET VAR =％1
最后设置=一些命令抢到％VAR％的最后一个令牌
回声％，去年％
出口
 

从本质上讲，我需要能够始终抓住最后一个令牌，在这些例子中，我会想抓住有一个从例子1和 2 从例子2

其他信息：

这不是命令行参数的问题，这仅仅是一个简单的例子：

的情况是，我打电话命令一个批处理文件内，将其输出发送给一个变量，像这样：

C：\\ execbatch.bat内存或 C：\\ execbatch.bat CPU

然后在批处理文件：

  FOR / F令牌= *%%我在（'C：\\ MONITOR.EXE -C custom_performance_counter -t％1 -w 80 -c 90'）不要设置COMMANDOUTPUT = %%我回声％COMMANDOUTPUT％
设置CurrentValue的一些=命令抢到％COMMANDOUTPUT％的最后一个令牌
echo当前值为％CurrentValue的％
 

这将输出取决于检查类型不同的结果;然而，在任何情况下的最后一个令牌/变量始终尽管无论是数字或单词的当前值。

解决方案

 关闭@echo集VAR1 =这是一个字符串
设置VAR2 =％VAR1％
集I = 0：loopprocess
FOR / F令牌= 1 *%%的（％VAR1％）在做（
  集/ A I + = 1
  设置VAR1 = %%乙
  转到loopprocess）呼应字符串包含％I％令牌。FOR / F令牌=％I％%%的G（％VAR2％）并设定最后= %%摹回声％，去年％暂停
 

In a batch file, how can I get the last token in a variable regardless of whether it is a number or a word and regardless of how many tokens/words there are in the variable.

I will be passing an argument into the batch file like this:

C:\execbatch.bat "This is example one" or C:\execbatch.bat "This is example number 2"

And then the batch file will be like this:

@echo off

SET var=%1
SET last=some command to grab the last token of %var%
echo %last%
exit

Essentially, I need to be able to always grab the last token, in these examples, I would want to grab one from example 1 and 2 from example 2.

ADDITIONAL INFORMATION:

It is not the command line arguments that are the issue, that was just a simplified example:

The case is that I am calling a command inside of a batch file and sending its output to a variable like so:

C:\execbatch.bat memory or C:\execbatch.bat cpu

And then in the batch file:

For /F "Tokens=*" %%I in ('c:\monitor.exe -C custom_performance_counter -t %1 -w 80 -c 90') Do Set COMMANDOUTPUT=%%I

Echo %COMMANDOUTPUT%
Set CURRENTVALUE=some command to grab the last token of %COMMANDOUTPUT%
Echo "The current value is %CURRENTVALUE%"

This will output various results depending on the check type; however in every case the last token/variable is always the current value albeit either number or word.

解决方案

@echo off

set var1=This is a String
set var2=%var1%
set i=0

:loopprocess
for /F "tokens=1*" %%A in ( "%var1%" ) do (
  set /A i+=1
  set var1=%%B
  goto loopprocess )

echo The string contains %i% tokens.

for /F "tokens=%i%" %%G in ( "%var2%" ) do set last=%%G

echo %last%
